I have setup a new HDP(3.1) cluster by enabling the kerberos. While running sample pi job it is failing with the error message. I have set the umask value to 022 in the shell before running the sample job. I have removed the appcache completely and rerun the job. But still the issue is there. If i disable kerberos then the job finishes successfully. Please let me know what could be the reason it will be very much helpful.   hadoop jar /usr/hdp/3.1.0.0-78/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 1 1   Error Message   19/08/27 23:15:37 INFO mapreduce Job: Task Id : attempt_1566659439835_0013_m_000001_2, Status : FAILED [2019-08-27 23:15:35.443]Application application_1566659439835_0013 initialization failed (exitCode=255) with output: main : command provided 0 main : run as user is projadmin main : requested yarn user is projadmin Path /hadoop/yarn/local/usercache/projadmin/appcache/application_1566659439835_0013 has permission 700 but needs permission 750.
